Sydney-style rollers sit differently on the hull than a standard keel roller. This 6-inch black rubber version (Viking 91230) is built for that profile — 17mm bore, soft rubber compound, budget price. It'll do the job. Just know it's soft enough to leave a light mark on a fibreglass or painted surface. For a quick haul-out or yard work where you're not worried about a faint scuff, grab this one
